AFX-50® is a set accelerator based on pure alumina, specifically designed for Portland-cement-based applications. At relatively low dosages between 3.5 and 7%, depending on the formulation and the desired effect, setting times can be reduced from several hours to less than half an hour.
Thanks to its unique formulation, not only will AFX-50® reduce setting and drying times, it will also provide a significant increase in early strength development.
As AFX-50® can be applied in relatively low dosages, it is a lot easier to apply in existing formulations than other alternatives such as special cements, which will often require a much higher dosage and the addition of other additives such as retarders.
